Description
Descrizione Description
Il presente trovato riguarda prodotti cosmetici atti a consentire la protezione dai raggi del sole della pelle del viso e del corpo umano. The present invention relates to cosmetic products suitable for allowing the skin of the face and the human body to be protected from the sun's rays.
Sono noti da tempo dei prodotti atti a consentire tale tipo di protezione. Products have been known for some time to allow this type of protection.
In particolare detti prodotti contengono sostanze cosiddette filtri solari le quali, applicate sulla pelle, sono tali da modificarne le reazioni negative provocate dai raggi ultravioletti (UV ) determinando opportune variazioni delle proprietà ottiche o fotochimiche dei raggi stessi. In particular, said products contain so-called sun filters which, when applied to the skin, are such as to modify the negative reactions caused by ultraviolet (UV) rays, causing suitable variations in the optical or photochemical properties of the rays themselves.
Tra i prodotti più usati come filtri solari vanno citati, in particolare, i derivati dell'acido para-amino benzoico, i derivati dell'acido orto-araino benzoico, i derivati dell'acido cinnamico, i derivati dell'acido salicilico, i derivati di natura terpenìca, i derivati del benzofenone, i derivati dell'acido gallico, i derivati dell'acido acrilico, i derivati del benzoimidazolo. Among the products most used as sunscreens we should mention, in particular, the derivatives of para-amino benzoic acid, the derivatives of ortho-araino benzoic acid, the derivatives of cinnamic acid, the derivatives of salicylic acid, the derivatives of a terpenic nature, benzophenone derivatives, gallic acid derivatives, acrylic acid derivatives, benzoimidazole derivatives.
Questi prodotti, nonché altri simili ai suddetti, sono in grado di assorbire esattamente la banda di energia caratteri tica delle radiazioni eritematogene per la cute. These products, as well as others similar to the aforesaid ones, are capable of exactly absorbing the characteristic energy band of the erythematogenic radiations for the skin.
A questo proposito è stato introdotto il cosiddetto fattore di protezione, consistente in un numero che indica di quante volte può essere prolungato il tempo di esposizione della pelle al sole prima che si verifichi l'eritema solare e cioè, in pratica, la scottatura, dovuta alla reazione della cute in risposta a determinate dosi di radiazioni solari di lunghezza d'onda nella banda compresa tra 280 e 320 nra. In this regard, the so-called protection factor has been introduced, consisting of a number that indicates how many times the time of exposure of the skin to the sun can be prolonged before sunburn occurs and that is, in practice, sunburn, due to to the reaction of the skin in response to certain doses of solar radiation with a wavelength in the band between 280 and 320 nra.
In pratica i prodotti che vengono commercializzati per la protezione dai raggi del sole sono costituiti da preparazioni in forma di emulsione acqua in olio (A/0) o olio in acqua (O/A) oppure geli acquosi o lipidici, oppure ancora soluzioni idrofile o lipofile contenenti filtri solari in grado di proteggere la cute dalle radiazioni ultraviolette. Detti filtri solari devono essere inseriti nel prodotto cosmetico seguendo determinati e precisi criteri . In practice, the products that are marketed for protection from the sun's rays are made up of preparations in the form of emulsion water in oil (A / 0) or oil in water (O / A) or aqueous or lipidic gels, or hydrophilic solutions or lipophilic containing sunscreens capable of protecting the skin from ultraviolet radiation. These sunscreens must be inserted into the cosmetic product following certain and precise criteria.
Nel caso in cui si abbia a che fare con sostanze liposolubili o idrosolubili, esse devono essere disciolte accuratamente, rispettivamente nella fase oleosa e nella fase acquosa del prodotto, sempre all'inizio della lavorazione In the event that we are dealing with fat-soluble or water-soluble substances, they must be carefully dissolved, respectively in the oily and aqueous phase of the product, always at the beginning of processing.
Questi accorgimenti devono essere attentamente seguiti al fine di garantire una dispersione perfettamente omogenea dei filtri nel prodotto finito evitando in tal modo che l'assorbimento delle radiazioni solari da parte del prodotto cosmetico si esplichi in maniera disomogenea sulla cute con il rischio di lasciare scarsamente ricoperte alcune zone cutanee. These precautions must be carefully followed in order to guarantee a perfectly homogeneous dispersion of the filters in the finished product thus avoiding that the absorption of solar radiation by the cosmetic product is unevenly expressed on the skin with the risk of leaving some poorly covered skin areas.
In particolare all'interno dei prodotti contenenti filtri liposolubili deve altresì essere inserita una quantità non inferiore al 5% di lipidi apolari per consentire la formazione di un film uniforme ed in grado di veicolare omogeneamente i filtri UV. In particular, a quantity of not less than 5% of apolar lipids must also be inserted inside the products containing liposoluble filters to allow the formation of a uniform film capable of homogeneously conveying the UV filters.
Per quanto riguarda l'attività dei filtri solari è noto che, con l'esposizione della pelle al sole, essi agiscono in quanto, per la loro struttura chimica, sono in grado di assorbire determinate radiazione prima che queste raggiungano la superficie cutanea. As regards the activity of sunscreens, it is known that, when the skin is exposed to the sun, they act because, due to their chemical structure, they are able to absorb certain radiations before they reach the skin surface.
In particolare, come già detto in precedenza, sostanze aventi strutture chimiche del tipo di quelle sopra menzionate sono in grado di assorbire le radiazioni della lunghezza d’onda dei raggi ultravioletti, cosiddetti UVB, compresa tra 280 e 320 nm. In particular, as already mentioned above, substances having chemical structures of the type mentioned above are able to absorb radiation of the wavelength of ultraviolet rays, so-called UVB, between 280 and 320 nm.
Ebbene le molecole di filtro solare, con l'assorbimento delle radiazioni, sono destinate a trasformarsi in composti eccitati e di consguenza maggiormente reattivi rispetto a quelli dai quali derivano . Well, the solar filter molecules, with the absorption of radiation, are destined to transform into excited compounds and consequently more reactive than those from which they derive.
In questa forma esse interagiscono velocemente sia con l'ossigeno, che con le altre sostanze con le quali si trovino in contatto o che siano presenti sulla superficie cutanea o facenti parti del veicolo cosmetico . In this form they interact quickly both with oxygen and with other substances with which they are in contact or that are present on the skin surface or forming parts of the cosmetic vehicle.
E quindi inevitabile che la molecola di filtro prima o poi reagisca e pertanto degradi divenendo quindi inattiva ai fini dell'assorbimento dei raggi ultravioletti compresi nella banda di cui sopra. Di conseguenza la protezione dalle radiazioni eri tematogene del prodotto cosmetico solare viene garantita all'inizio, ma decresce progressivamente con il prolungarsi dell'esposizione alle radiazioni solari . It is therefore inevitable that the filter molecule sooner or later reacts and therefore degrades, thus becoming inactive for the purpose of absorbing the ultraviolet rays included in the above band. Consequently, the protection from the anti-thematogenic radiation of the solar cosmetic product is guaranteed at the beginning, but progressively decreases with the prolongation of exposure to solar radiation.
Nel campo della cosmesi sono state inoltre ideate le cosiddette microsferule , costituite da elementi in grado di inglobare sostanze in forma fluida e di rilasciare il loro contenuto in maniera graduale progressiva una volta giunte a contatto con la pelle . In the field of cosmetics, the so-called microspheres have also been devised, consisting of elements capable of incorporating substances in a fluid form and releasing their contents in a gradual and progressive manner once they come into contact with the skin.
'In particolare esse possono presentare una struttura vescicolare e allora prendono il nome di microcapsule , costituite da un involucro di gelatina o da una struttura polimerica di vario tipo (lattice, polmetilmetacr ilato ) ed il cui contenuto viene liberato per rottura di detta capsula di rivestimento . In particular, they can have a vesicular structure and then take the name of microcapsules, consisting of a gelatin casing or a polymeric structure of various types (latex, polmethylmethacrylate) and the contents of which are released by breaking said covering capsule .
Alternativamente la microsferula può avere una struttura multìporosa e quindi il suo contenuto può essere liberato per cessione progressiva attraverso la matrice. Alternatively, the microspherule can have a multi-porous structure and therefore its contents can be released by progressive release through the matrix.
All'interno delle microcapsule possono essere poste soltanto sostanze di tipo oleoso, oppure sostanze sciolte in olio. Only oily substances or substances dissolved in oil can be placed inside the microcapsules.
Il processo, di tipo in sè noto, viene realizzato mediante sospensione del materiale da incapsulare in acqua e con successiva deposizione di uno strato di gelatìna che costituirà l'involucro, seguito da solidificazione della membrana gelatinosa per trattamento termico. The process, of a per se known type, is carried out by suspending the material to be encapsulated in water and with subsequent deposition of a layer of gelatìna which will form the envelope, followed by solidification of the gelatinous membrane by heat treatment.
Viceversa la microspugna, detta generalmente "entrapped forra" è costituita da una matrice polimerica porosa inerte attraverso la quale viene fatto assorbire il principio attivo che può, in questo caso, essere sia di tipo acquoso che oleoso Il presente trovato riguarda la realizzazione di prodotti cosmetici per la protezione della pelle del viso e del corpo dai raggi solari, che siano in grado di proteggere l'utente da radiazione eritematogene in modo più efficace rispetto ai dispositivi consimili di tipo noto. Vice versa, the microsponge, generally called "entrapped gorge" consists of an inert porous polymeric matrix through which the active principle is absorbed which can, in this case, be both aqueous and oily type. The present invention relates to the production of cosmetic products for the protection of the skin of the face and body from the sun's rays, which are able to protect the user from erythematogenic radiation more effectively than similar devices of a known type.
Ciò si ottiene, secondo il trovato, prevedendo dei prodotti cosmetici del tipo sopra descritto, nei quali i filtri solari vengono rilasciati in modo graduale, in modo da mantere inalterata la capacità di assorbimento delle radiazioni solari da parte del prodotto durante l'esposizione al sole, al fine di garantire una protezione costante per tutta la durata dell'esposizione stessa. This is achieved, according to the invention, by providing cosmetic products of the type described above, in which the sunscreens are released gradually, so as to maintain the product's ability to absorb solar radiation unaltered during exposure to the sun. , in order to guarantee constant protection for the duration of the exposure itself.
In particolare i filtri di protezione dalle radiazioni solari saranno posti all'interno delle microsferule, sia sotto forma di microcapsule, che sotto forma di microspugne del tipo descritto in precedenza. In particular, the solar radiation protection filters will be placed inside the microspheres, both in the form of microcapsules, and in the form of microsponges of the type described above.
I filtri potranno essere presenti nei prodotti solamente in forma microsferulata oppure anche in associazione alla forma libera. The filters may be present in the products only in microsferulated form or also in association with the free form.
Per quanto riguarda le microcapsule previste per contenere il filtro solare esse dovranno essere accuratamente disperse in una piccola quantità di prodotto che verrà poi aggiunto al "batch" di produzione previo raffreddamento dello stesso sotto i 50°C (vantaggiosamente sotto i 40eC), al fine di evitare la denaturazione e degradazione dell'involucro delle microcapsule che avviene al di sopra di tale temperatura. As for the microcapsules provided to contain the solar filter, they must be carefully dispersed in a small amount of product which will then be added to the production "batch" after cooling it below 50 ° C (advantageously below 40eC), in order to to avoid denaturation and degradation of the microcapsule envelope that occurs above this temperature.
Disponendo comunque i filtri entro le microsferule, sia sotto forma di microcapsule, che sotto forma di microspugne è possibile prevedere che il rilascio dei filtri stessi sia estremamente lento in modo da rifornire continuamente la superficie della pelle della protezione necessaria. However, by arranging the filters inside the microspheres, both in the form of microcapsules and in the form of micro-sponges, it is possible to foresee that the release of the filters themselves is extremely slow so as to continuously supply the skin surface with the necessary protection.
In particolare è possibile prevedere delle forme ad azione protratta che racchiudono al loro interno il filtro rendendolo pertanto non disponibile immediatamente; essi hanno la proprietà di liberarlo soltanto dal momento in cui decresce la concentrazione sulla pelle. In particular, it is possible to provide forms with protracted action which enclose the filter inside them, making it therefore not immediately available; they have the property of freeing it only from the moment in which the concentration on the skin decreases.
In questo modo viene mantenuto costante nel tempo il grado di assorbimento dei raggi solari promesso dal prodotto. In this way, the degree of absorption of solar rays promised by the product is kept constant over time.
Risulta pertanto evidente il vantaggio per 1 'utilizzatore che consiste in una costante completa garanzia della protezione solare, cosa questa che, come già visto in precedenza, non è mai offerta dai 'prodotti per la protezione solare di tipo noto. The advantage for the user is therefore evident, consisting in a constant complete guarantee of sun protection, something which, as already seen above, is never offered by known types of sun protection products.
La presenza del principio attivo anti UV nella duplice forma microsferulata e libera è auspicabile per una gamma completa di prodotti cosmetici che si prefiggono di assicurare e mantenere per molte ore la protezione della pelle dal sole (ad esempio una linea composta di latti, creme solari per il viso e per il corpo eleoliti, geli, unguenti con fattori di protezione alti, medi o bassi ecc.) The presence of the anti-UV active ingredient in the double micro-spherulated and free form is desirable for a complete range of cosmetic products that aim to ensure and maintain the protection of the skin from the sun for many hours (for example a line composed of milks, sun creams for face and body eleoliths, gels, ointments with high, medium or low protection factors, etc.)
